Methods for the repair of damaged low k films are provided. Damage to the low k films occurs during processing of the film such as during etching, ashing, and planarization. The processing of the low k film causes water to store in the pores of the film and further causes hydrophilic compounds to form in the low k film structure. Repair processes incorporating ultraviolet (UV) radiation and silylation compounds remove the water from the pores and further remove the hydrophilic compounds from the low k film structure.

An “on-demand” approach for a routing protocol for a wireless network that achieves balanced energy consumption among all participating nodes in the network. Synchronization messages transmitted by nodes associated with an upstream node include local node information (LNI) that a node can use to repair or bypass a lost upstream node in a real or virtual (temporary) manner depending upon the local node's battery level. Only if a repair process fails will a global re-organization (Re-Org) be initiated. The LNI also allows for nodes having lower power availability (battery level) not to transmit the LNI so that unaffiliated node(s) can select an upstream node having more power availability thereby extending network life.

The present invention provides an apparatus and method for an adaptive machining and weld repair process useful for repairing airfoils, particularly damage to an airfoil leading edge and tip. The process first machines away damaged portions of an airfoil. Filler material is then added to the machined area through a process such as laser welding. At this point, the actual profile of the welded airfoil is measured using a Coordinate Measuring Machine. This data is then used to generate a “deformation” profile, an airfoil profile that approximates the ideal shape of the airfoil. The airfoil is then machined using the date of the deformation profile to produce that shape. The adaptive technology minimizes the amount of stock on material that needs to be removed by hand. The technique thereby significantly reduces costly manual processing.
